UNITED STATES ATENT JAMES BLUNDELL, OF SOUTHPORT, ENGLAND.

CORKSCREW.

SPECIFICAIIN forming part of Letters Patent No. 644,700, dated March 6,1900.

Application filed Agst 19, 1898. Seral No. 689,040. (No modal.)

T0 aZZ whom it may conoern:

Be it known that I, J AMES BLUNDELL, a subject of the Queen of GreatBritain, residing at 64 Kensington road, Sonthport, in the connty ofLancaster, England, have invented a new and useful Improvement inCorkscrews, (for which I have applied for a patent in Great Britain, No.12,039, dated the 27th of May, 1898,) of which the following is aspecification.

My invention relates to corkscrews to be used by hand, and has for itsobject to render them more efficient in use and more convenient.

In using an ordinary corkscrew as hitherto usnally constructed it isnecessary to remove the hand from the handle after each tnrn thereof andto regrasp said handle, and this is liable to shake the bottle and itscontents. A corkscrew constructed according to my invention obviatesthis disadvantage, as well as being more rapid in use, inasmnch as Whenonce the handle is grasped a to-and-fro motion thereof drives the screwinto the cork. The screw is connected to the handle, so as to turn oneway only with relation thereto, by means of a ratchet-and-pawl device,and a detent is provided whereby relative motion may be entirelyprevented When it is desired, in order that the cork may be removed fromthe screw by unsorewing in the usual manner.

In the drawings, Figure 1 is a vertical section through my corkscrcw.Fig. 2 is an elevation at right angles to Fig. 1. Fig. 3 is a plan, thecap 19, hereinafter described, being removed.

lis the handle, preferably of cast metal, its two arms being bored out,as shown. It has a depending bored-ont trunk 2, provided with a guard 3.

4 is the screw proper, rigidly attached to or formed in one with therevolving spindle 5.

6 is a ratchet-wheel rigidly attached to spin dle 5, and 7 is its pawl.

8 is the stem or tail of pawl 7,havingsquared end 9 Sliding in washer 10in the handle, and 11 is its spring. 12 is a screw-plug to close thatend of the handle. At the other end of the handle I provide a stem 13,carrying a detent 14, normally kept out of engagement With ratchet-wheel6 by spring 15 and having a finger-button 16 on its projecting end. Thisdotent 14 is adapted to enter notches 17 made between the teeth ofratchet-wheel 6. (See Fig. 3.) 18 is a screw-plug to close this end ofhandle 1.

The hollow in the top of handle 1 is closed by a removable cap 19, and areversed foot- Step bearing thereon cakes np the thrust of spindle 5.

In action whcn it is desired to withdraw a cork from a bottle the pointof screw 4is pressed against it and the handle 1 is partially rotatedbackward and forward. On its forward stroke the screw 4 is turned byreason of pawl 7 meshing with ratchet-whecl 6; but on the return strokethe end of pawl 7 rides idly over the teeth. The cork is withdrawn bypulling in the ordinary way, and when it is wished to remove it from thesorew 4 finger-button 16 is pressed and detent 14 thus caused to meshwith a notch 17 in ratehet-wheel 6. The screw 4 and handle 1 being thusheld relatively rigidly, the cor]: may be removed as usnal.

What I claim as my invention, and desire to secure by Letters Patent,is-

In a corkscrew the combination of handle 1, hollow trunk 2 dependingtherefrom, spindle 5 located and free to revolve in said trunk, screw 4attached to said spindle, ratchet-wheel 6 rigidly attached to saidspindle, a springactnated pawl 7 to prevent rotation of said spindle inone direction while allowing rotation in the other direction, a detent14 supported on a stem 13, a spring 15 whereby detent 14 is heldnormally out of engagement with ratchet 6, and a button 16 on theprojecting end of said stem, whereby When pressure is applied theretothe revoluble parts are locked, snbstantially as described.
